I think this pull request is not necessary any more. Please see my comment in #57.

I think it fixes some of the problems. My comments are in #57.
It also contains fixes unrelated to #57 for the following issues:

  1. Deadlock at Scheduler::isSleeping() check.
  2. Retrying timed out system calls for the remainder of sleep time when transitioning to FF mode.
